ENVELOPE.

Application filed. October 15, 1923. Serial No. 668,756.

My invention relates to improvements in envelopes.

The object of my invention is to provide a novel envelope adapted to be used for both first class and second class mail at the same time. My improved envelope provides two pockets adapted to contain respectively two kinds of mail and also adapted for respectively containing photographic negatives and prints.

A further object of my invention is to provide an envelope which is cheap to make, simple in construction and which is easily manipulated.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates thepreferred embodiment of my invention,

Fig. 1 is a perspective view of my improved envelope shown ready for use.

Fig. 2 is a perspective'view, showing the flaps folded.

Fig. 3 is an enlarged sectional view on the line 33 of Fig. 1.

Fig. 4 is a perspective view of the envelope prior to the intermediate and end portions being doubled to form the two pockets.

Fig. 5 is a plan view of a blank (reduced) from which my improved envelope is adapted to be formed.

Similar reference characters designate similar parts in the different views.

1 designates two oppositely disposed end portions, which in the making of the envelope are folded over the intermediate portion 2 along the lines ab and ccZ respectively, the end portions 1 being overlapped and fastened together by gumming or otherwise.

After the end portions 1 are so fastened together, they and the intermediate portion 2 are doubled along the line ef, Fig. 4, so as to form two pockets 3 and 4, Figs. 1 and 3. The pocket 3 is adapted to be closed by two flaps 5 with which the portions 1 are respectlvely provided at their upper ends. The flaps 5 may be gummed for sealing purposes, in the usual manner.

The intermediate portion 2 is provided at its upper end with a closing flap 6, which is adapted to be folded over and to close both pocket-s 3 and 4. It may also be gummed for sealing it to the end portions 1. The flap 6 is also adapted to be inserted in the pocket 4, when said pocket is to contain second class mail.

The flaps 5 may be preliminarily folded in the process of making along the line g-h, Fig. 4, for the convenience of the user. In a like manner and for a like purpose, the flap 6 may be folded in the process of manufacture along the line z'j, Fig. 4.

In the manufacture of the envelope from the blank shown in Fig. 5, the end portions 1 are first folded over the intermediate portion 2 and fastened together, after which the portions 1 and 2 are doubled, thus forming the pockets 3 and 4. The portion 2 is folded along the line g72,, Figs. 4 and 5, which is above the upper edges of the flaps 5, to enable the flap 6 being fastened to the end portions below the flaps 5, when desired. When the pocket 4 is used for second class mail, and is unsealed, it may be inserted in the pocket 4. The pocket 3 is intended for first class sealed mail, and, when so used, the flaps 5 are folded over the pocket 3, and are gummed to the end portions 1 below the pocket 3.

The flap 6 is of greater vertical width than the flaps 5 for the function of being gummed to the end portions below the flaps 5, as stated, and for the further purpose of supporting exposed to view a stamp 7, Fig. 2, when the flap is inserted in the pocket 4 and the latter contains second class mail. In such case, the postage for the first class mail contained in the pocket 3 is carried by one of the flaps 5, as indicated by the stamp 8 in Fig. 2.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention. By fastening together the portions 1 and 2, solid unbroken walls are provided for adjacent sides of both pockets 3 and 4.

lVhat I claim is 1. An envelope comprising two end portionsand an intermediate portion, each portion having a closing flap, the end portions being folded over the intermediate portion and fastened together, the intermediate portion and the end portions being doubled to form two pockets, the flaps of the end portions being adapted to be folded over and close one of the pocriets, and the flap of the intermediate portion he mg adapted to be folded over both pockets.

2. An envelope comprising two end portions and an intermediate portion, each portion having a flap, the flap of the inter mediate portion having greater vertical Width than the other two flaps, the end p0rtions being folded over the intermediate portion and fastened together, the intero e flap of the intermediate portion being a lepted to be folded over both of said ockets.

In testimony whereof I have signed my name to this specification.
